Global carbon (C) emissions from fossil fuel use were 9.795 gigatonnes (Gt) in 2014 (or 35.9 GtCO2 of carbon dioxide).  Fossil fuel emissions were 0.6% above emissions in 2013 and 60% above emissions in 1990 (the reference year in the Kyoto Protocol).

Based on a 2015 GDP forecast of 3.1% by the International Monetary Fund, the Global Carbon Project projects a 2015 decline of 0.6% in global emissions.
